I almost went this route last year. I was looking at Sunsetter (they get good reviews and I know a family member that bought one and loves it). Motorized retract, etc. If you are a Costco member you can order through them for special pricing, and once a quarter or so their coupon book includes some form of Sunsetter coupon.
Quick advice: get a long piece of wood (or even a skimmer pole) and stick it straight off your house where you expect the awning to be installed. See where the shadow ends up at certain times of day. This will help you determine where the awning will actually provide cover from the sun. The reason I didnt buy ANY awning was because at the peak time of the day where were going to install it, the angle of the sun would have basically made half of the awning useless....just the right angle so that the sun got under the far edge of it starting at about 2PM and going until the sun was completely set. Naturally, thats about the time most people are out enjoying the pool! But that tip (originally from my Dad) saved me about $2K
